3 In Mechanical Pipe Plug
The Cherne 271535 is a mechanical pipe plug designed to seal the end of a 3 inch nominal pipe. It fits inside diameters ranging from 2.86 inches to 3.25 inches and is constructed from galvanized steel for corrosion resistance. This tool provides a temporary or permanent seal during testing or maintenance.
Use for low-pressure air or water tests
Suitable for plumbers and contractors performing low-pressure pipe testing or isolation where back pressure does not exceed 2 PSI air or 5 feet of head water. Not intended for high-pressure applications or situations requiring a larger sealing range than the specified diameter limits.
Sealing range 2.86 to 3.25 inches
The plug fits pipes with an inside diameter between 2.86 inches and 3.25 inches, making this the critical specification for selection. Verify the pipe internal diameter before purchase to ensure a proper seal. The galvanized steel body withstands the rated back pressures.

Questions about this item
How do I install the Cherne 271535 mechanical plug in a 3 In trap and what step is often missed?
Insert the plug so the pipe ID falls between 2.86 In and 3.25 In, then tighten the mechanism until the galvanized steel body seals evenly; the step often missed is verifying the seal at low pressure before applying full back pressure.
What maintenance or replacement will the Cherne 271535 plug need over time?
Inspect the galvanized steel body and sealing surfaces for corrosion or wear after each use; replace the plug if the metal shows pitting or the mechanism no longer expands to 3.25 In.
What limit appears first when the Cherne 271535 plug is under sustained back pressure?
The 2 PSI maximum back air pressure rating is reached before the 5 ft of head water pressure limit, so sustained air testing will hit the lower threshold first.
